Keep a good earth element crucial questions of 7: Ma Shifeng published: "The new farmers", "farmer technology", "scientific breeding" 1. How formulated keeping the soil? Earth element of life in the soil-feeding, with good soil is the key to keeping farming soil elements. In fact, keeping the soil preparation is very simple, take the garden wall of mellow and Chen soil, the soil crack or crush with a 4 mm sieve look, plus 40% of burnt rice husk (Longkang) ash mixing uniform humidity requirements for hand-shape into the free fall that is scattered groups, can be put to use. If you can add the right amount of maturity home store manure, sawdust, straw, so keeping the soil fertile, loose, the better. 2. Temperature and humidity during the growth earth element is what? Earth element Growth humidity have a greater relationship with the temperature, the larvae temperature is 28 ℃ ~ 32 ℃, relative humidity of 40% ~ 50%, the temperature is about insects 28 ℃, relative humidity of 50% ~ 60%, destroyer temperature is 25 ℃, relative humidity of 60% to 70%. 3. How earth element feed preparation? Earth element larvae feed as follows: 45% wheat bran, soybean meal or soybean meal 3%, 2% of animal feed, forage 50% (pumpkin, cabbage, carrots, etc.); the insects feed as follows: 40% wheat bran, soybean meal or soybean powder 5%, 5% corn flour, green fodder 50%; Beast (spawning worms) feed is: 35% wheat bran, soybean meal or soybean meal 5%, 5% animal feed, corn flour 5%, 50% green fodder. = 4. Earth element in what temperature should be heated? Aquaculture earth element most suitable temperature for 25 ℃ ~ 32 ℃, if less than 20 ℃ requires heating, heating requirements can not fluctuated, requiring balance. 5. Earth element pond indoor Why should replace the air? Earth element in the breeding process, should pay attention to indoor air fresh (especially the contradiction between the winter heating and ventilation, ventilation must be carefully grasp timely, and does not affect the temperature). The main element is the large number of earth exhaled carbon dioxide, so ventilation can not be ignored. If people into the feed room feel nausea, malaise, it means that the air is not normal. Usually 24 hours a day, every 6 to 8 hours 10 minutes of ventilation (ventilation of soil yuan room doors must be open at both ends) 6. How to manage insects lay eggs? Earth element farmed spawning process is more stringent pest management, stocking density to be more sparse, usually not more than 5000 per square, this time not only for the big humidity requirements, and require more fresh air, the optimum temperature is 25 ℃ ~ 26 ℃, feed requirements nutritious animal feed increases, increase forage regulate moisture, keeping the soil increased thickness is 15 cm or so, spawning insect feeding soil moisture requirements can not afford to over 4 mm sieve group prevail. 7. Earth element timely harvest should? When the female worms grow and mature, significantly reduced the number of eggs, we should promptly with 8 mm sieve out in the worm into the boiling water scalded to death, remove and put water in the washing clean, then put the sun to dry up . Requires no soft earth element belly substances Note: Select Harvest earth element conduct fine weather, faster, disposable harvest a large number of consecutive days the harvest can not be mixed together. If consecutive rainy days, drying methods should be taken not to make earth element deterioration, mildew.
